  • ATM Asynchronous Transfer Mode
  • FIG. 1 is a schematic diagram of the ATM mode access of ADSL/VDSL2 in the conventional art.
  • an ATM mode adaptation is performed in an ADSL/ VDSL2 Customer Premise Equipment (CPE) for the datagram of the subscriber, and the subscriber data is borne on the ATM link layer.
  • CPE Customer Premise Equipment
  • a common central office access device usually accesses a subscriber device such as a Personal Computer (PC) in the ATM mode, and the CPE also employs the ATM mode.
  • PC Personal Computer
  • FIG. 2 is a schematic diagram of the PTM mode access of VDSL2 in the conventional art. As shown in Figure 2 , a Packet Transfer Mode (PTM) based on packet bearer is newly added in VDSL2. The PTM mode is a mode for the future Ethernet access, and the link layer is encapsulated in the Ethernet format.
  • PTM Packet Transfer Mode
  • the service layer should be instructed to implement the automatic service configuration directed to the port when the physical layer of the VDSL2 line of the access device AN identifies the operation mode, because in the ATM mode, the ATM cell is received by the port, and the service configuration and processing are mainly based on the ATM cell, whereas in the PTM mode, an Ethernet packet in the PTM mode is received by the port, and the service configuration and processing are mainly based on the Ethernet packet. Therefore, the service layer should perform automatic adaptation according to the mode identified by the
  • US2003/0135596 discloses a customer premise network configuration.
  • the customer premise network configuration is provided to enable a new service within the network by a network configuration manager.
  • the network configuration manager is either manually or automatically invoked upon a new service being used in the network.
  • the configuration manager obtains a service template for the service, which template provides generic end-to-end requirements for enabling the service.
  • a configuration generator generates vendor-neutral device-configuration settings from the service template.
  • a service configuration validator module then validates the service.
  • an adaptor module translates the vendor-neutral device-configuration settings to vendor specific configuration settings corresponding to the devices in the network and configures the devices.
  • US6878505 discloses An application implemented at customer premises equipment automatically for detecting the network-layer protocol used at the head end of a DSL connection and configuring the DSL modem driver for that protocol.
  • the application sets the DSL modem driver to one of the possible protocols for the type of driver being used and attempts to connect to a server at the head end. If a response is received from the head end, then the application reads the headers on the responsive message to determine whether the protocol at the head end is consistent with the protocol that the DSL modem is set to. If the protocols are consistent, then the settings are loaded onto the driver. If no response is received from the head end when the application attempts to connect to the server, then the application initiates a series of commands for the purpose of eliciting a response from the head end.
  • the DSL modem is set to another protocol, and the application again attempts to connect to the server at the head end. These steps are repeated until either the correct head-end network-layer protocol is found, or the possible protocols are exhausted
  • US2003/0041237 discloses an integrated access device for being automatically configured to conduct packetized voice and data communications between a customer's voice/data equipment and a digital communications switch.
  • the IAD's communication control processor is programmed to perform an automated analysis of the digital communications link and thereby identify communication interface circuits such as DSLAM and voice gateway units, that have been installed by the service provider. It then automatically configures the communication parameters of the IAD for communication compatibility with the communication interface circuits.
